Saving loop values as column vector

I have a very simple loop that gives out values for d. How would I make it so that these values are saved to a 1 by n matrix?

c=6.25;
x=2.5;
>> for loop = 1:25
d=c-(c^-2+x*c)
c=d;
end

d = zeros(1,25);
c = 6.25;
x = 2.5;
for loop = 1:25
    d(loop) = c-(c^-2+x*c);
    c = d(loop);
end
